Automotive Powertrain and Emissions Control Laboratory

Automotive Powertrain and Emissions Control Laboratory equipment

The Automotive Powertrain and Emissions Control Laboratory was established by Dr. Pingen Chen in 2016. The main research areas of focus are modeling, diagnostics, controls, and optimizations of various automotive systems including conventional/hybrid/electric powertrains, internal combustion engines, emissions control systems, sensors, autonomous vehicles, and advanced engine combustion with alternative/renewable fuels.

Key Capabilities:

  • Control of lean-burn gasoline engine and passive SCR systems
  • Fully integrated control of diesel engine and aftertreatment system applications
  • Engine combustion with alternative/renewable fuels and flexible-fuel powertrain control
  • Automated and connected vehicle development and controls
  • Nonlinear control theory
  • Optimization of electric vehicle operation and charging strategies
  • Engine and aftertreatment system configuration optimization
  • Catalyst aging and diagnostics
